Q9Y6H8

Protein name

Gap junction alpha-3 protein (Connexin-46) (Cx46)

Protein function

Structural component of lens fiber gap junctions (PubMed:30044662). Gap junctions are dodecameric channels that connect the cytoplasm of adjoining cells (By similarity). They are formed by the docking of two hexameric hemichannels, one from each
